13, 26, 39, 52, 65, 78, 91.
The multiples of 8 less than 100 are: 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96. These numbers are obtained by multiplying 8 by integers from 1 to 12.
The multiples of 5 that are also multiples of 6 are multiples of their LCM. The LCM of 5 and 6 is 30, so the question becomes which multiples of 30 are less than 100? The solution is the numbers: 30, 60, 90

A number that is not a multiple of 7 and is less than 100 is 23. To determine this, we can list multiples of 7 (such as 7, 14, 21, 28, etc.) and check for numbers below 100 that do not appear in that list. Since 23 is not divisible by 7, it fits the criteria perfectly.
44 and 88 are the only common multiples of 4 and 11 that are less than 100
